Since April this year, the new 2 MW crowdfunded solar park in Spain from Som Energía has been producing power. It is unique because it has no subsidies and because the energy is sold to the retail cooperative, so the price is supplied at cost* to the investors.

I’m proud of having participated in this project. It’s sustainable, doesn’t need subsidies and also a good investment. The funding will be returned with no interest, but the benefit is through the reduced energy costs in the retail monthly invoice.
Living in a flat with little space for solar panels, I find it very difficult and inefficient to install one or a couple of self-consumption solar panels. So this is a natural option, to team-up with other people to own together renewable power generation. And it avoids facing the so-called tax on the sun (discussed some time ago here).
Of course there are other investment options like Yieldcos (I have shares from Saeta Yield myself). Or simply buying 100% renewable electricity from the retailer. But helping build this small project with a cooperative feels closer to owning the plant. And power generation not only owned by big corporations is also positive, as has been the case in Germany. We can say it’s a good example of the sharing economy, too…
What other options do you see to participate as an individual in the energy transition?
*Actual calculation is 36 €/MWh, which means 6 €/MWh below the market before taxes and network charges.
It’s official. Finally Spain has the most toll-intensive consumer power generation (what is called self-consumption) law in the world. The so-called “sun tax” is in place.
It is important to understand the worries of the regulator here;
Given the high fixed costs of the system, further reductions of electricity demand (as with self-consumption) increase the price of energy in a Grid independence cycle. The goal of increasing the toll on self-consumption is to ensure the system costs are covered, delay the implementation of self-consumption (starting in the islands and small systems), delay consumer energy storage (in fact it is also a “battery tax”) and (try to) avoid further political problems. Of course, it is not the best solution, academics and regulatory experts agree that politically fixed costs that have to be paid by all citizens shouldn’t be in the tariff but evenly paid from the nation’s bugdet (like the extra-costs for electricity in the islands).

What are the consequences? Rising prices, and the fact that fixed costs (for the contracted power) are surging, push the active consumer to look for the following solutions:
As commented in a recent post on renewable islands, to completely decarbonize islands, it is necessary to use renewables for electricity and heating, together with the electrification of transport. (Actually, electric mobility serves as renewable storage)
By transport I mean electric mobility on land, that is vehicles, rail, buses, but also on the sea. How can we decarbonize sea transport?
No, I’m not proposing getting our hands on the oars or going back to:

I have decided to create a category in my blog devoted to “breakthrough” inventions that are due to revolutionize the energy landscape…
Every once in a while we get to read about products or systems that are unbelievable, and sometimes feel like a joke. My recommendation is to avoid prejudices and have an open mind for innovation. You don’t want to discard progress without a proper analysis!
Having said that, let’s have a look at this system; CSV: “Captors of Sun and Wind”, consisting in 2 solar panels, hanging on a vertical post with a balancing system…
You must admit the system is kind of hypnotizing…With the typical slow balancing movement that generates sooo much power 😉
To analyze this kind of system we can consider the following: Sigue leyendo →
Solar panel manufacturing has benefited from economies of scale in the race to lower the costs, following an impressive learning curve (see BNEF curve). But will the future bring the cheapest solar panels, being printed where needed from a simple and cheap device?
This is already happening in manufacturing, as described brilliantly by Chris Anderson in Makers. With technology already available for printing solar cells on paper, innovation improving efficiency and durability, is set to revolutionize solar panel manufacturing. Centralized production would be complemented by local micro-manufacturing.
Solar photovoltaics is today the best example/solution for democratization of power generation, as it allows simple and scalable self-consumption. Democratizing also the manufacturing of the panel would take it a step further, boosting solar generation capacity well above the actual double digit yearly growth.
